Actualy he is right. Who told you to use Promods in a map combo? Of course, how do you expect their edited FLD prefabs to match with ORIGINAL FLD pack used by other maps? It's our fault.
The old Red Sea map, the new SR 10 map and the new ATS Reforma map .
I supose you know that Red sea map in version 1.2.2 and SR hotfix above SR 10 final (both links in first page) solve the problem with excesive load time.
New Reforma 2.1.3 solve the loading time too in ATS
